NTAG203 NFC Forum Type 2 Tag compliant IC with 144 bytes user memory

NXP Semiconductors has developed NTAG203 - NFC Forum Type 2 Tag compliant IC - to be used with NFC enabled devices according to NFC Forum technical specifications, according to NFC Forum recommendations or Proximity Coupling Devices (PCD), according to ISO/IEC 14443A. The communication layer (RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. The NTAG203 is primarily designed for NFC Forum Type 2 Tag applications (i.e. Smart Advertisement, connection handover, Bluetooth simple pairing, WiFi Protected set-up, call request, SMS, goods and device authentication and others).

Contactless energy and data transfer

Communication to NTAG can be established only when the IC is connected to a coil. Form and specification of the coil is out of scope of this document.

When the NTAG is positioned in the RF field, the high speed RF communication interface allows the transmission of the data with a baud rate of 106 kbit/s

产品特点 Features

RF Interface (ISO/IEC 14443A)

Contactless transmission of data and supply energy (no battery needed)

EEPROM

168 bytes of total memory, divided in 42 pages (4 bytes each)
144 bytes of user r/w memory area, divided in 36 pages (4 bytes each)
Field programmable read-only locking function per page for first 64 bytes
Field programmable read-only locking function per block
32-bit user definable One-Time Programmable (OTP) area
16-bit counter
Data retention of 5 years

NFC Forum Tag 2 Type compliance

NTAG203 IC provides full compliance to the NFC Forum Tag 2 Type technical specification and enables NDEF data structure configurations.

Security

Anti-cloning support by unique 7-byte serial number for each device
32-bit user programmable OTP area
Field programmable read-only locking function per page for first 512 bits
Read-only locking per block for rest of memory

Cascaded UID

The anticollision function is based on an IC individual serial number called Unique IDentifier. The UID of the NTAG203 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.

Anticollision

An intelligent anticollision function according to ISO/IEC 14443 allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field
